STEAM-PLOWING.

SPECIFICATION forming part of Letters Patent No. 255,587, dated March28, 1882,

' Application filed July 9,1881. (No model.)

dentofthe cityofBerlin,Prussia, in theEmpire of Germany, have inventedcertain new and useful Improvements in Steam-Plowing; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same,

reference being had to the accompanyingdrawiugs, which form apart ofthis specification, and in which-- Y Figure l is a side elevation of myimproved locomotive-engine for operating the plow or plows. Fig. 2 is aplan view of the same with the boiler removed. Fig. 3 is a diagramrepresenting the method of operating the plow or plows where two enginesare used. Fig. 4 is a side elevation of the anchor with its carriage andappurtenances. Fig. 5 is a plan or top view of the same. Fig. 6 is aside view of the anchor and carriage, showing the former in its elevatedposition. Fig. 7 is a diagram representing the method of operating theplow or plows by a single engine and its anchors; and Figs. 8, S, and 8represent details of the snatch-block carriage which is used with theanchor.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to plowing by steam with one or two stationaryengines; and it consists in the improvements hereinafter set forth, andparticularly pointed out in the claims.

'1 shall first describe the engine and its up purtenances, and thenproceed to describe the use of the same, according to whether it isdesired to use two engines oronly one. The construction ofthe cngiucsisthe same whethertwo or one is, used.

Reference being had to Figs. 1 and 2 of the drawings, the letter Arepresents an iron frame, preferably of rectangular shape, upon whichare placed the boilerB, cylinder 0, coal-bins D, and water-tank E. Theframe is supported upon a pair of traction-wheels, a, and swiveled frontwheels, at, the shaft or axle of the traction-wheels being soconstructed and arranged that itmay be coupled or uncoupled at will'withthe engine, so that the latter may be used to propel the machine to andfrom the field of operations.

Upon a shaft,f, mounted in one end offrame A, is a pair of drums orvertical windlasses (shown at Faud F) provided with concentricgear-wheelsengaging with pinions on the driveshaft of the engine, sothat either one may be operated at will.

Below the frame is ahorizoutal grooved pulley, G, and a'pair of groovedpulleys, H H, the two last-named being of like diameter and mounted upona common shaft or vertical axle.

Where two of these engines are used no further machinery is necessary tooperate the plow; but if one engine is to be used only, I employ thecarriage and anchor which are represented in the several figures onSheet 2 of the drawings.

The ground-anchor (shown at T) has three fiukes, T, and a shaft, J, theends of which have cranks K K, provided withstubaxles L L, by which theshaft and anchor are mounted upon a pair of light wheels, M M. Alever,O,is secured upon shaft J, so that by raising the lever from the positionshown in Fig. 4 to that represented in ,Fig. 6 the flakes of the anchorwill be pulled out of the ground. At the end of the shank or beam T is ahook for coupling it to the pulley-carriage, to be hereinafterdescribed, and also a bench or support, N, as shown.

The pulley-carriage, or snatch-block carriage, is mounted upon two pairsof swiveled wheels, I and I,its frame consistingesseutially of ahorizontal bed-plate, Q, and parallel top plate, Q.

I? is the horizontal pulley-wheel or snatchblock, the short verticalshaft of which. journaled in bearings in the plates Q and Q, has apinion, b, which meshes with a cog-wheel, of, having a small concentricpulley, 0. An endless chain, d, connects pulley c with another largerhorizontal drum or pulley, R, mounted fixedly upon a vertical shaft, 8,in the front end of the carriage. Upon this shafts slides a loose drum,S, which may be adjusted up or down by means of the bent lever U, so asto occupy any one of three different positions upon shaft 8, as shownmore clearly on the three detail views marked respectively Figs. 8 8 and8 on Sheet 2 of the drawings. The adjustable drum S is recessedconcentrically in its top and bottom to adapt it to engage with aclutch, t, which is fixed in the bedpla-te Q, or a clutch, t, which isfixed upon the under side of and moves with the pulley R.

It follows that when the drum S is in the position shown in Fig. 8 itwill remain fixed or stationary, (held by the fixed bottom clutch, t,)while shafts and pulley R revolve. Ifin the position represented in Fig.8 it is disengaged from both clutches t and t, while if in the positionshown in Fig. 8 it engages with the top clutch, t, and rotates withpulley It. The lever U may be fixed in any one of its three positions bya spring-catch, which engages with a rack-bar, u, as shown in Fig. 4,where drum S is shown in its down or fixed position.

Fastened to and wound around this drum is a band, V, at the free end ofwhich is a link or eye, W, which may be hooked upon the anchor-hook, thebench or support N of the latter keeping it on an elevation with drum S,as shown clearly in Fig. 4 of the drawings.

When two engines are used in operating the plow I proceed as follows,reference being had to the diagram shown in Fig. 3, in which the lettersX and Y represent the two engines located in a line with one another atopposite sides of the field, and 2 represents the gang of plows drawnforward and back between them.

A chain or wire rope (designated by l) is attached at one end to theplow, and then passes around the horizontal sheave or pulley G,underneath engine X, and up around the windlass F, in which its otherend is fastened. Another chain or rope, III, is in like manner attachedto the other side of the plow and carried around pulley G of the sisterengine, Y, and up around and secured in its windlass F. Fastened in theWindlass F of engine X is another chain or rope, II, which passes fromsaid Windlass down and around the horizontal sheave or pulley H, andthen across the field, as shown by the arrow, to the pulley H of theopposite engine, Y, and, passing around this pulley, its free end issecured to the plow. The fourth and last chain (indicated by IV) startsin like manner from the windlass F of engine Y, passes down and aroundpulley H of said engine, and then across the field to pulley H of engineX, and around said pulley back to the plow z, to which it is fastenedopposite to the fastening-point of chain II.

Supposing the plow to go in the direction of the large arrow, markedx,it will thus be seen that it is drawn by the chain I ofengine X andchain IV ofengine Y, while, when, after reaching the end of its track,its course is reversed, it is drawn by chain IlI. of engine Yand chainII of engine X. At the end of each course both engines are moved forwarda distance corresponding to the width of the set or series of furrowslast made by the plow.

Where one engine only is used and the anchor and snatch-block carriagecome into play, the operation is as follows, reference being now had tothe diagram shown in Fig. 7 of the drawings: Two anchors (designatedrespectively by Z and Z) are placed at one end of the field, at adistance apart corresponding to the width of two sets or series offurrows as made by the gang of plows, which is in this vented fromwinding off by the drum S being adjusted by lever U in its downposition, engaging with the fixed bottom clutch, t. When, after the plowhas completed its course, the engine is moved forward, the band V isunrolled by shifting drum S into its middle position, (shown in Fig. 8and the link or eye W is shifted to the hook of the next anchor at Z, asshown by the dotted line. This done, the engine is started, the drumbeing at the same time shifted by lever U to the position represented inFig. S -that is, coupling with clutch t of the revolving sheave orpulley R, which rotates the drum and winds up the band, thus drawing thecarriage into the position shown in dotted lines, parallel to its formerposition. Anchor Z is'now lifted and placed above Z, ready for the nextcourse of the plow, and so on, the snatch-block carriage being securedalternately to the two anchors, which are alternately shifted tocorrespond to the progress of the engine over the field.

llaving thus fully described my invention, I claim and desire to secureby Letters Patent of the United States of America- 1. The snatch-blockcarriage mounted upon swiveled wheels I I, and composed of a frame, Q Q,sheave I, having pinion b, cog-wheel 0, having concentric pulley a, bandd, shaft 8,

sheave or pulley R, keyed upon said shaft, and

provided with the clutch t, band-drum S, vertically adjustable uponshaft 8, means for adjusting said drum, clutch t, fixed in the bottomplate, Q, of the carriage-frame, and band V, having the link or eye W atits free end, constructed and combined substantially as and forthepurpose herein shown and specified.

2. The combination, with a fixed pair of anchors, Z Z, of a snatch-blockcarriage, engine, and chains connecting the snatch-block with theengine, as described, so that after the band which connects thesnatch-block carriage with anchor Z has been shifted to and coupled withthe next anchor, Z, the snatch-block carriage may be drawn into itsoperative position in a line with anchor Z and the engine by theoperation of the latter and the chains which connect it with thesnatch-block, substantially as and for the purpose herein shown and setforth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
